Like most, I can do without the fireworks display but if it's good for the tracks attendance I'm OK with it even if it is a couple of extra bucks. I don't think they could delay until the racing is over. The kids that come for fireworks would be asleep, or too sleepy to enjoy them. Only takes a few minutes. I've been at Bloomington on fireworks night when people (not race attendees) were parked on the road outside the track.
